Our invention has relation to a method of and apparatusQfOr use innthe coating of castings. 'The inventionhas been particularly designed for use in connection with the manufacture of enameled, metal flushtank bodies, lavatories, sinks, etc., and is designed to providea methodand means by which the time and labor involved-in the coating operations are greatly reduced.

Heretofore, inapplying first coatings to articles of this character, the castings have been brought from the cleaing room to the 1 coating room. They are then placed on end in position to enable a portion of their sur- 'faces to be coated by the use of an air brush Or gun. The castings are. then turned over so that the remaining surfaces to be.

as are shown in the Shafler Patent No.

1,261,446, dated April 2, 17918. To receive these hooks each side ofeach support is pro:

-VlCl6d near the top with a'transversely-extending plate or cleat 5 having sockets-6 for engagement with the hooks. The cleats can be of the same pattern as those used for sup porting the tanks when they are installed.

In this manner two of the castings can be held on each of the supports 3, one on each side thereof, in the inclined shown in the drawings. A r

In operation the castings, after being cleaned in the cleaning room are placed on the trucks in the positions shown and thetrucks are then carried to the coating room.

positions as I To facilitate moving the'trucks, they may;

be provided with castor wheels 7. Itwill V readily be seen that both the interior and exterior surfaces of the articles to be coated are exposed so that both surfaces may be coated without in any way lifting or handling the castings. Theoperator with the usual air brush or slush gun first coats the interior of each casting and then the exterior. The trucks with the coated castings thereon can then be taken to the baking ovens,

Figure 5 we have shown how lavatories may be placed on the same supports for coating, with all surfaces thereof which re uire coating exposed.

y reason of our invention the operator who does the coating is entirely relieved of all work of handling the castings. This not only makes his work much easier, but greatly increases the output of the factory. The castings are sufficiently spaced on the supports so that the'operator can readily reach them with his brush, this also being facilitated by the staggered arrangement of the twosets of supports. I

It will be readily understood that the particular form of supports can be widely varied, the essential thing being that they shall be provided with means whereby the castings can be held 'in position to be coated without necessity for handling them during the coating operation. It is also preferred that the supports shall be of a portable character so that they can be moved from place to place with the articles thereon preparatory to and after coating. It is not essential that all articles shall be held in in-* cline d positions. For instance, in Figures 6 and 7 we have shown a support which may be used in coating sinks and lavatories which do not require to be coated on the back and underside, In this figure, 8 designates a supporting member extending lonjgitudinally of the truck, and having supporting cleats 9 on 'OPPOSllZB sides, similar to the cheats 5 before described and with me a ns castings to be coated upon a movable support having means for cooperation with the i on the castings to hold said castings in position on the support in substantially the manner in which they are supported in use and with both the eXteriorand interior surfaces-to be coated exposedand accessible for the coating operations, and coating such surfaces while so supported and without changing their positions during coating, substantially as described. 1
